gabrielfiuza is on a distinguished road
I am doing simple simulations with 2D airfoil NACA0012 in Fluent to determinate the Cd and the Cl. After generating the mesh (tetrahedral) and established the parameters (Spalart-Almaras model, ideal gas), I initialized the calculation, but each iteration is taking about 8 minutes to show!!!
How do I solve this?

Obs: I am solving in parallel with 4 cores and double precision.
